Investigating sleep quality and related factors of postoperative patients at Tay Nguyen Regional General Hospital, Dak Lak Province, Vietnam

Abstract

As we know, sleep is very important and necessary for every person. Especially, among patients undergoing surgery as an effective form of treatment, they also need a good quality of sleep to restore both physiological and psychological health. However, poor sleep quality is common in patients after surgery and produces harmful effects on postoperative recovery. This study was conducted to investigate the quality of sleep and identify related factors among postoperative patients at the Department of General Surgery, Tay Nguyen Regional General Hospital, Dak Lak Province. A cross-sectional descriptive study was performed. 374 postoperative patients who meet the sampling criteria were recruited by simple random sampling between March and July 2021. General information data were collected through interviews with structured questionnaires, and the patient’s sleep quality was assessed by using the Pittsburgh Sleep Quality Index (PSQI) Vietnamese version. Data analysis was performed via SPSS ver 20.0; p < 0.05 was statistically significant. The average mean of PSQI score was 10.3 ± 3.27 (range = 0 -21, SD = 3.27). The percentage of postoperative patients who had poor sleep quality was 78.1%. Factors associated with poor sleep quality include old age (p < 0.01), education level (p < 0.05), level of postoperative pain (p < 0.001). The frequency of poor sleep quality among postoperative patients is high. The findings of this study also provide a better understanding of related factors that affect poor sleep quality. So, the nurses should develop an appropriate care plan to improve sleep quality in these patients by controlling the above factors. It will help these patients recover fastest and most comprehensively in the postoperative period, enhancing the quality of care.
